trates my invention.

Similar letters of reference indicate corresponding part-s.

A represents .the door. base. ion for preventing the concussion orslamming of the door. The holder consists of a stud, E, which is securedinto or attached to the wall or base, so as to be permanently fixed B isthe wall or thereto. F is a spring-catch, which is pivoted in thelateral branch G of the main stud E. The branch piece G is slotted toreceive the catch. H is the pivot-pin. The back end I of this catch hasa slot, J, through which passes a screw, K, which enters the side of thestud E. Around this screw is a spiral spring, L, which is confinedbetween the stud and the catch, against which it bears with a O is thedoor-holder, and D isthe cush constant pressure to force the catch.against the head of the screw. When the door is opened and thrown back,it strikes the bevel end 0 of the catch and forces the latter backagainst the pressure of the spring at the other end. The catch acts as aspring-latch and catches onto the door, as seen in the drawing. Allconcussion of the door is prevented by the cushion D, which is :made ofrubber, or similar soft and yielding substance, and fixed to the end ofthe stud E. The slotted hole J allowsthe back end of this catch to movewithout binding. The power of the spring is simply sufficient to keepthe catch in vposition for acting upon the door.

With this device a door may be swung back without noise and held in themost secure and perfect manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A door-holder consisting. of the' stud E, branch G, catch F, fulcrum-pinH, screw K, spiral spring L, and slot J arranged to operate as and forthe purposes described.
